Abstract: 27,123. Schwehm, P. Dec. 9. Gas engines.-Gas and air are supplied to a twostroke cycle engine by separate pumps 7, 8 provided with receiving or pressure-equalizing chambers 9, 10. The gas and air valves 1, 2 are concentrically arranged and independently operated, the valves, valve-chamber, and combustion chamber 4 being rounded, as shown, so that the scavenging-charge of air may act uniformly on the area of the cylinder while driving out the exhaust gases. The piston and rod end are also rounded, as shown, in the case of a double-acting engine, to direct the gases gradually towards the exhaust ports 5. In a single-acting cylinder, the open side of the piston may be flat. One pair of pumps may supply more than one gas engine, as at a power station. The engine may be regulated by varying the opening of the valves or by throttle valves 6 in one or both of the supply pipes. To prevent excessive pressure in the chamber 9 due to throttling by the governor &c., the two sides of the gas pump piston are connected by a passage normally closed by valves, which are opened by a spring-loaded piston in the delivery pipe when the pressure rises sufficiently. Or the suction and delivery pipes may be connected by a pipe normally closed by a spring-loaded valve, which opens to allow part of the gas to return to the suction pipe.

Granted: 1903-11-19
Abstract: 1070. Efrem, O., and Schwarz, R. Jan. 15. Arc lamps.-Clutches in the form of eccentrics or wedges grip the carbons when the solenoid core rises, and release the same when the core sinks. Fig. 1 shows a form in which the clutch frame c, which is rigidly secured to the core, has eccentrically mounted in it a disc a provided with a bent gravity arm d, so' that its weight tends to cause the pulley to grip the carbon f. Thus, when the core rises the carbon also rises, but when, owing to the diminution of the current strength, the current flows through the secondary coil g<1> and the core b and clutch c fall till the arm d comes into contact with the disc h, the pulley is turned and releases the carbon. Fig. 3 shows a form of clutch in which a conical ring c<2> works over jaws a', which are also tapered. When the core rises, the jaws a<1> are tightened over the carbon f, and raise it. When the core falls, the jaws a' come in contact with the stop plate h, and release the carbon.

Title: Method of Ejecting Rock Cuttings from Holes in Rock while Drilling them.
Inventor: LEYNER JOHN GEORGE
Filed: 1904-03-14
Granted: 1904-09-01
Abstract: 6183. Leyner, J. G. March 14. Rock drills.-In percussive drills actuated by compressed air or the like, part of the motive fluid, together with water under pressure, is conveyed near the cutting-point of the drill, and delivered into the hole during the drilling operation to lay the dust, and to expel the dÚbris. The invention is shown as applied to a drill with a loose tool spindle, which is struck by a separate reciprocating piston. The water is supplied from closed tanks, placed at suitable points, by means of the pressure of the air which drives the drills, or by other means. The rotating gear and the feed are also described, the constructional features being given in some detail. The tool or tool spindle 20 is carried by the sleeves 3, 4 in the front cylinder head so that it can be struck by the loose piston. The outer sleeve 4 is held in the cylinder head by a collar and spring 28, while a U or staple piece 33 fits in its forward end to prevent the spindle from falling out, but allows of its ready removal. The inner sleeve bears on a spring buffer 9, and is shaped internally so that the spindle can slide but cannot turn in it. In order to turn the tool, the sleeve 3 has two or more rods 11 projecting into the piston, which is turned by a usual rifle-bar arrangement. The feed-screw works through a thrust bearing K carried by rods T from the cradle. Water is admitted to the hollow tool by a tube 18 passing through the rifle bar and piston, and attached to the back cylinder head, where a valve 43 controls the supply from a hollow ring 50, which is rendered water-tight by washers and nuts 54, though it can be turned to place the water inlet in a suitable position. Part of the compressed air or motive fluid from the forward end of the cylinder passes down the tool together with the water.

Abstract: 14,245. Warwick Machinery Co., [General Electric Co.]. June 23. Steam &c. turbines.-The parallel-flow elasticfluid turbine described has amongst other features intermediate and wheel buckets and diaphragms between the wheels. The main shaft 1, Fig.1, has mounted upon it sleeves 2, 3, each of which is provided with two wheel discs 4 located in separate compartments. The wheel buckets 5 attached to the faces of the wheels revolve on each side of the intermediate buckets attached to supports 13 formed on the undersides of projections 12 forming part of the casing 6, which is made in segments. The upper end of the casing is provided with a shoulder to receive the cover 7 which contains the valve-chests 8, in each of which are several separately-actuated valves 9 which control the admission of motive fluid and are actuated by a governor. Between the wheels 4 are diaphragms 11 mounted on projections 12, the faces 19, 20 of the diaphragms being smooth and in close proximity to the buckets so as to reduce rotation losses, for which purpose also projections 18 with smooth inner surfaces close to the buckets are formed on the diaphragms. The underside of the diaphragm is cut away to receive the nozzle-plate 14, and the upper side is provided with chambers 16 which extend circumferentially as far as the nozzle 14 and are strengthened by ribs 17. Inclined passages 21, Figs. 1 and 2, communicate with a groove 22 in the diaphragm and discharge water given up by the expanding steam into a gutter 23 communicating with an adjacent stage or wheel-chamber by a vertical passage 24, Fig. 2, which may have a valve 25. The diaphragm has a central portion cut out to receive carbon packing 26 provided with a holder 27, with which engages a spring 28 under a plate 29. The cover 7 is also provided with suitable packing-rings 30. In Figs. 2 and 3, the ribs 17 are shown flush with the surface of the diaphragm. Water discharged through the clearance passes through openings 32, strikes the inclined surface of the diaphragm, and is deflected into the gutter. In the chambers 33, the steam is somewhat removed from the whirling effects of the wheel and is given an opportunity of discharging its moisture due to expansion.
Patent GB-190414357-A (GB)
Title: Improvements in Mechanism for the Production of Fringes in or on Fabrics in Weaving Looms.
Inventor: HADDAN HERBERT JOHN
Filed: 1904-06-25
Granted: 1905-03-23
Abstract: 14,357. Haddan, H. J., [Puig, R.]. June 25. Loom dobbies; jacquards; take-up motions.-In looms for weaving fringed fabrics, when a fringe is to be formed, the operation of the shedding- mechanism is automatically stopped, and the take-up of the fabric is accelerated. The sprocketchain N<1>, Fig. 4, for controlling the operation of the healds, is traversed by means of a ratchetwheal P' and a fixed pawl O<1>. The ratchet-wheel is mounted on a bar R, which is free to slide in guides Q on a rocker S. The rocker is oscillated about its pivot S<1> by means of a rod T' and cam T, so that the ratchet-wheel P<1> is actuated by the pawl so long as it is in engagement therewith. The bar R is connected by a link K to a bell-crank lever J" J' J, of which the arm J is engaged between abutments on a rod E<1> connected to a pivoted lever E. A nose D on the lever rests upon a drum I, which is rotated by spur gearing or otherwise and has a slot A. When the fringe is to be produced, the nose enters the slot and the lever E is lowered, so that, through the rod E<1> and the bell-crank lever and link, the bar R is moved to the right and the ratchet-wheel P<1> is moved away from its pawl. If a weft-pile &c. fabric is to be produced, a ratchet-wheel P, for traversing a sprocket-chain N, is brought into engagement with its pawl O by the use of a second drum, such as I, having a deeper slot. The sprocket-chain N controls shedding-mechanism for producing a weft-pile fabric &c. When the invention is applied to a jacquard loom, the rod E<1> is arranged to stop the action of the jacquard by any mechanical means. In order to accelerate the take-up of fabric when the action of the shedding- mechanism is stopped, the cloth beam may be driven from a ratchet-wheel Z, Fig. 5, which is actuated by the arm X<1>1 of a lever pivoted on a lever X<1>. This lever is pivoted at X<111> , and is connected by a link Q<1> to one of the lay-swords U, so that the arm X<1>1 is constantly vibrated. The arm X<1>1 is normally held out of engagement, with the ratchet-wheel by a spring Y, but, when the lever E is lowered, the other end of its lever is raised by a rod X and a pivoted lever V" V connected to the lever E, so that the ratchet-wheel is actuated by the arm X<1>1.

Title: Improvements in Brickmaking Machinery and such like.
Inventor: WALLIS GEORGE PEARSON
Filed: 1904-06-28
Granted: 1905-06-01
Abstract: 14,502. Wallis, G. P., and Broadley, J. R. June 28. Moulding bricks &c.-In cylinder machines with diametrical pistons, lamination of the clay is prevented by holding the pistons fixed when required. This is accomplished by means of a cam acting on the piston-heads, or, as in the four-mould cylinder shown, by providing bars I fixed in the pistonheads and movable in slots H. The clay forced in at position 1 drives out a moulded form in position 3, so that the piston-head there comes to the periphery of the cylinder. The race L acting on the bars I prevents the piston from moving inwards between the positions 4, 1, so that no clay is forced in till the mould is directly opposite the mouth A, when all the material comes in as a steady stream.
